Setup PyTorch

PyTorch is a popular open-source deep learning framework, renowned for its dynamic computation graph that enhances flexibility and ease of use, making it a preferred choice for researchers and developers. With strong community support, PyTorch facilitates seamless experimentation and rapid prototyping in the field of machine learning.

Prerequisites

  • Ensure nerdctl is available on all cluster nodes.

  • If GPUs are present on the target nodes, install NVIDIA CUDA (with containerd) or AMD Rocm drivers during provisioning. CPUs do not require any additional drivers.

  • Use local_repo.yml to create an offline PyTorch repository.

[Optional prerequisites]

  • Ensure the system has enough space.

  • Ensure the inventory file includes a kube_control_plane and a kube_node listing all cluster nodes. Click here for a sample file.

  • Nerdctl does not support mounting directories as devices because it is not a feature of containerd (runtime that nerdctl uses). Individual files need to be attached while running nerdctl.

Deploying PyTorch

  1. Change directories to the tools folder:

    cd tools

  2. Run the pytorch.yml playbook:

    ansible-playbook pytorch.yml -i inventory

Note

During the pytorch.yml playbook execution, nodes with AMD or NVIDIA GPUs and drivers will install and test either the pytorch-AMD or pytorch-Nvidia containers, respectively. If neither GPU type is present with its drivers, it will install and test the pytorch-CPU container.

Accessing PyTorch (CPU)

  1. Verify that the PyTorch image present in container engine images:

    nerdctl images

  2. Use the container image per your needs:

    nerdctl run -it --rm pytorch/pytorch:latest

Accessing PyTorch (AMD GPU)

  1. Verify that the PyTorch image present in container engine images:

    nerdctl images

  2. Use the container image per your needs:

    nerdctl run -it --cap-add=SYS_PTRACE --security-opt seccomp=unconfined --device=/dev/kfd --device /dev/dri/card0 --device /dev/dri/card1 --device /dev/dri/card2 --device /dev/dri/renderD128 --device /dev/dri/renderD129  --group-add video --ipc=host --shm-size 8G rocm/pytorch:latest

Accessing PyTorch (NVIDIA GPU)

  1. Verify that the PyTorch image present in container engine images:

    nerdctl images

  2. Use the container image per your needs:

    nerdctl  run --gpus all -it --rm nvcr.io/nvidia/pytorch:23.12-py3
